I would like to know if it is possible to link a view with the top "Create button" of a custom module given that this button isn't a part of any view.

Now when I click on this button Odoo opens a new row that I have to fill but I would like to open a view (or a wizard) in order to add this new entry.

I have been told that this process is done in JS ?

The form when we click on "Create" from the quotation page would be perfect but I can't find how it is done.
